She said weekend weather all but depleted supplies and crews were still in conservation mode, only salting hills and intersections. Jeannette and Unity Township's public works directors said they too were conserving supplies and will continue to plow roadways.

In Hempfield Township, public works director Mike Volpe said a lack of communication with salt suppliers left him wondering if he would receive the truckloads of salt he was awaiting.

"You'd think with a half-decent weekend our supplier would be shipping to everybody who is having salt emergency, they didn't even work this weekend," Volpe said. "Us municipalities out here are just left high and dry, back order after back order."

Volpe said they were expecting another 150 tons of anti-skid from a different supplier. If the township didn't receive a salt shipment today, crews would have to use their emergency salt supply, which is 400 tons.

"All our supplies we got last week, we used. They were all used up over the weekend," Volpe said.

Murrysville police and Hempfield Emergency Management issued travel advisories for the next 24 hours due to approaching weather. Both agencies are requesting drivers avoid unnecessary travel as road crews in those communities are low on salt and anti-skid.
